Mail setup

Mail in UserGate can be set up by either of these two methods: Port mapping or Network Address Translation (NAT).

With this method, mail programs connect to UserGate Proxy Server, which, in turn, forwards user requests to the specified mail servers on the Internet. Thus, for each mailbox on the Internet it is necessary to create two port mappings: SMTP and POP.

Select Port mapping in the UserGate setup menu.

Pressing the Add button on the Control panel or selecting the Add New option in the pop-up window, launch the dialogue window to create a new port mapping.

Enter SMTP port mapping settings ( illustration):

• Mapping name - for example, "Smtp on yahoo.com".
• Listen IP - Any, or specify the internal network interface on which UserGate will listen to user requests.
• Listen Port - any free port (for example 8025).
• Destination address - mail server address, for example: smtp.mail.yahoo.com.
• Destination port - mail server port, for example: 25.
• Used protocol - network protocol to use, in most cases 'TCP'.

The second port mapping for pop protocol is set up in the same way ( illustration):

If in the "Authorization of port mapping" section a certain user is specified, Authorization of this user in UserGate will not be performed (for example, this will be applied in case the user is authorized by login name and password).

With the mail setup by Port Mapping, it is important to set up the mail programs properly, i.e. the appropriate addresses of computer with UserGate must be specified as SMTP and POP servers.

( illustration for The Bat).

This is the easier way of mail setup. To make a mail program work, you must assign to a user or a group of users two NAT rules: SMTP and POP. In this case the work of the mail program on the Internet is transparent and the settings are the same as if you were working on the Internet directly ( illustration):

UserGate Proxy Server has a list of predefined NAT rules, which also contain mail rules. To make the rules work, specify interfaces of sender and receiver and set up DNS.
